If you want my opinion, THE true luxury SUV remains the Range Rover. But it wasn't made in 2005 so... Yeah.
Okay, I'm gonna address the elephant in the room. These polls are stupid. The last few you did were pretty pointless. Somehow, you managed to make this one even worse. Both of the options were steaming piles of crap. A Trailblazer rebadge and a Ford Explorer rebadge aren't luxury cars. You didn't even include the best Trailblazer rebadge, the Saab 9-7x.
Easily the 1967 Daihatsu Compagno Spider. Never before have I seen a car that exuberates the given niche known to some as a "2005 Luxury SUV" Just look at this pie chart. Have you ever seen a pie chart lie? No you haven't have you now My vote goes out to the 1967 Daihatsu Compagno Spider!
